Title: Method and circuit for phase holding
Inventor: YAMAMOTO KOJI
IPC: H03L7/14
Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To easily operate a circuit at high speed by making a phase difference from a synchronous clock source smaller and a phase fluctuation smaller at the time of HOLDOVER when a time of HOLDOVER becomes long with respect to digital data sampled at the time of normal state. SOLUTION: In a phase holding method for holding a synchronous source clock of a synchronous digital hierarchy(SDH) device, digital data that sample the synchronous source clock signal at the time of normal state are stored in a storage means, the digital data of the storage means are selected when the clock cutoff is detected, and an oscillation pulse of a voltage control oscillator 11 is generated. Also, in the phase holding method, the digital data of the storage means are added and subtracted by data obtained by phase comparing the synchronous source clock signal with the oscillation pulse of the voltage control oscillator 11.

Title: Nuclear power generator
IPC: G21D5/08
Filed: 1992-03-13
Abstract: PURPOSE:To increase thermal efficiency without causing radiation leak by introducing the hot water from a reactor in the heater of a Stirling engine and using as the heat source. CONSTITUTION:The basic principle of a Stirling engine 1 is to output a motive force of up and down of a piston 7 by heating and cooling operation gas. When the hot water from a reactor 21 passes through a heater 2, the gas expands in the expansion space 5 in the upper part of a gas cylinder 13 to move a displacer 6 and the piston 7 downward. When it comes down to the lower dead point, it starts moving upward owing to the gas spring 8 between the rod 14 upper end and the displacer 6 and the repulse space 9 in the lower side. The expanded gas is cooled passing through a recoverter 4 and a cooler 3 and returns to a compression space 10. A magnet fixed on he piston 7 moves up and down together and thus the coil 12 surrounding the rod 14 generates electricity. By this, electricity generation efficiency is kept constant, radiation leak generation is reduced and safety and reliability in the electric generation system are ensured.

Title: Cleanerless electrophotographing method
Inventor: HOSHI NOBUYOSHI
IPC: G03G15/08
Filed: 1993-03-16
Abstract: PURPOSE:To prevent accumulation of remaining toner on a recording medium by applying development bias voltage at which the remaining toner can be recovered easily to a developing apparatus in non-recording areas of the recording medium. CONSTITUTION:A recording medium 1 which rotates clockwise and composed of a photoconducdtor is charged, for example, with positive charge uniformly, laser beam 3 modulated by image data is radiated to the medium to form a negative-type electrostatic latent image whose surface potential is V0 and remaining potential Vr and the image is developed by transfer development by toner 5 in a development apparatus 4. At that time, bias potential Vb which is intermediate between the surface potential V0 and remaining potential Vr is applied to the development apparatus 4. After the toner image 6 on the recording medium 1 is transferred to a recording sheet of paper 8, the remaining charge of the recording medium 1 is erased by an eraser 9, and the remaining toner 10 is removed to reuse the recording medium 1. In the non-recording areas, the surface potential is heightened to V0' from V0 and the bias potential is decreased to Vb' from Vb, so that the difference between V0' and Vb' is widened and thus the recovery of the remaining toner 10 is heightened.

Filed: 1990-03-07
Abstract: PURPOSE:To make it possible to discriminate a wide character area by sorting an area into three kinds of blocks in accordance with density differences and remarking the patterns of constitutional blocks in respective character and pattern areas to execute pattern matching processing. CONSTITUTION:An image data processing part 1 switches the image data of the three primary colors into parameters corresponding to pattern and character areas based upon the discrimination signals of respective areas, processes the parameters and outputs an image improved at the reproducibility of its patterns and characters. A block deciding means 3 sorts blocks consisting of plural picture elements into three sorts, i.e. white, character and picture blocks, in accordance with the frequency of white picture elements and the density differences of the picture elements in each block and decides the blocks of respective areas. A macro correcting means 4 executes the macro correction of the decision result of the remarked block by intra-window pattern matching with a peripheral block decision value consisting of a ternary value and divides the image into blocks each of which consists of plural picture elements. Since macro correction utilizing the block decision result is executed in addition to block decision, the accuracy of discrimination can be improved.

A period upper limit/lower limit discriminator 10 outputs a signal when the output of the counter 6 falls within the prescribed range. A number counting condition forming circuit 8 applies an outut signal to the counter 11 when both signals are inputted. When the value of the counter 11 becomes the prescribed value, a runaway detection signal is outputted.
